如何将zip文件发送到前端进行DRF下载

   # 生成并保存zip文件

   # ...

   # 读取zip文件并返回给前端

   with open('path/to/zipfile.zip', 'rb') as f:

       response = FileResponse(f)

       response['Content-Type'] = 'application/zip'

       response['Content-Disposition'] = 'attachment; filename="download.zip"'

       return response

   var xhr = new XMLHttpRequest();

   xhr.open('GET', '/api/download-zip/', true);

   xhr.responseType = 'blob';

   xhr.onload = function() {

       if (xhr.status === 200) {

           var blob = new Blob([xhr.response], { type: 'application/zip' });

           var link = document.createElement('a');

           link.href = window.URL.createObjectURL(blob);

           link.download = 'download.zip';

           link.click();

       }

   };

   xhr.send();

   fetch('/api/download-zip/')

       .then(response => response.blob())

       .then(blob => {

           var link = document.createElement('a');

           link.href = window.URL.createObjectURL(blob);

           link.download = 'download.zip';

           link.click();

       });
